GRAIN DRILL. y,

and VILMONT BILLS, citizens of the United States, residing at Dowagiac, county of Cass, State of Michigan, have invented certain `ncw and useful Improvements in Grain is clearly Drills, of which the following is a specification.

This invention relates to improvements in grain drills.

The main object of this `invention 'is to provide an improved grain drill which is veniently operated by the driver of the tractor. j

VFurther objects, and objects relating to structural details, will definitely appear from the detaileddescription to follow.

TWe accomplish the 'objects of our invention bythe devicesand means described. in thefollowing specification. The invention deiinedand pointed out `in the claims.v y

A structure which is afpreferred embodiment of our invention is clearly illustrated inf the accompanying drawing, forming a part of this specification.in which: I

Fig. I 1s arear perspective view of a grain 'i drill of thedisk type embodying the'features of .our invention, the grain boX and feed mech'anismvand a portion of the cover-v ing chains being omitted. Y Y Fig. II is an enlarged detail view on a line corresponding to line 2 2 of Fig. I.

.F ig. IH is an enlargeddetail view on av line corresponding to the broken line 3 3 of Fig. I, showing the arrangement of the auxiliary lift and pressure spring for the furrow openers.

Fig. IV is a detailside elevationof the pole draft connection. I

Fig. V is a horizontal section on a line corresponding to line 5 5 ofv Fig. I.

In the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, l. represents the main frame and 2 the carrying wheels. The

furrow openers 3 are of the disktype and are connected to the frame by the draw bars 4. The furrow opener adjusting rock shaft Specification of Letters Patent. j Patented API'. 25, 1922- Appncation filed July' 12,l 'Y

are connected by the links 7." Pressure springs 8 are provided on the links 7. Y

v An additional pressure and lifting means is provided consisting of the springs 9, thev rear ends of which are connected by the rods l0 to the cross pieces 11 carried by pairs of the arms 6, the forward ends of the springs v n being connected to the frame by the rods 12.

The operation of these springs is illustrated i in Fig. III. The parts described are shown more or less conventionally and they are not described in further detail as the arrange' ment thereof is o ld.

On the furrow opener adjusting rock shaft 5 we mount a worm segment V13 and above,` this a coacting worm 14e.V The worm 14' is provided with a shaft supported'at its 'Y front end by a bearing lfand mounted on the frame at its rearendbyabrack'et 17.`

This bracket 17 is bracedand supported by the bars l8extendingfromthe bracket tothe,"

frame. j

7e provide an actuating shaft 19 consist- Ving of telescoping sections 2O 'and 21,A thesection 2l being'conneeted to thejshaft 15A by a universal joint 22. jThis actuating' shaft 19 is adjustably supported by an L.-sha' pe'd bracket 23vboth arms of which are -provided with a plurality of boltholes. vThe hori-` zontal arm 'rests uponand is adjusta'blyse-A cured to the tongue 30 by' means of the bolt 24, while the bearing 25 for theV actuatingshaft is -adjust'ablyl secured to the vertical arm of the bracket by means ofthe bolt 26 which may be engagedin any onev ofzft'he,

several holes.

The lactuatingshaftis provided withlal crank 27 having an adjustable 'handpiece section 28 secured by the .bolt 29 so that the crank may be adjusted to regulate the length of its throw. The supporting bracketmay be reversed on the stub tongue 30 if desired. By providing an actuating shaft which may be conveniently lengthened or shortened and an adjustable support therefor-the parts may vbe adjusted to bring the crank into conven-` ient operating relation to the seat of a tractor, the position of which isV found to vary inthe different tractors on the market.`

f A draft connection, designated generally by the numeral 31, is provided for the trac- However, these Vdetails form' no partV of our present invention. f

W'ev have illustrated and ldescribed l our improvements 1n one practical embodiment g v nel thereof. We have not attempted to illustrate ci' describe other adaptations or embodiinents'which we contemplate as we believe the disclosure made will enable those skilled in the art to which our invention relates to embody or adapt the same as may be desired.

Having thus described our invention what we claim as new and desire to secure by Letters Patent, is: i

l. rfhe combination in a grain drill of the class comprising carrying wheels, a main frame, a tongue, draft connections, and furrow openers, of adjusting means for said furrow openings comprising a forwardly extending actuating shaft having sections telescoping for longitudinal adjustment, a crank for said actuating shaft provided with a handpiece -section adjustable to vary the length of the crank, an L-shaped supporting bracket having a plurality of bolt holes in each arm mounted on said tongue by a bolt on the tongue engaging a hole of the horizontal arm ofy the bracket so that the same may be'reversed or adjusted laterally on thel tongue, and a bearing for said actuating shaft secured to the bracket by a bolt engaging a hole of the vertical arm so that the shaft may be vertically adjusted.

. 2. The combination in a grain drill of the class comprising. carrying wheels, a main frame, a tongue, draft connections, and furrow openers, of adjusting means for said furrow openersvcomprising a forwardly eX- tending actuating shaft, an Lshaped supporting bracket having a pluralit.7 of bolt holes in each 'arm mounted on saidtongue by a bolt on the tongue engaging a hole of the horizontal' arm of the bracket so that the same may be reversed or adjusted laterally on the tongue, land a bearing for said actuating shaft secured to the bracket by a bolt engaging a hole of the vertical arm so that the shaft may begertically adjusted.

3. The combination in a grain drill of the class comprising carrying wheels, a main frame, a tongue, draft connections, and furrow openers, of a rock shaft' for adjusting said furrowy openers, a worm segment. on said rock shaft, a worm coacting with said segment, a forwardly extending actuating shaft for said worm and comprising sections telescoping for longitudinal adjustment, a crank for said actuating shaft provided with a handpiece section adjustable to vary the length of the crank, an l.shaped supporting bracket adjustably and reversibly mounted on said tongue, and a bearing for said actu-k ating shaft adjustably mounted on said bracket. Y

et. The combination in a grain drill of the class comprising carrying wheels, a main frame, a tongue, draft connections, and fur- 5. rlChe combination in a grain drill of theV class comprising carrying wheels, a main frame, a tongue, draft connections, and furrow openers, of a rock shaft for adjusting said furrow openers, a worm segment on said rock shaft, a worm coacting with said segment, a forwardly extending actuating shaft Y for said worm and comprising sections telescoping for vlongitudinal, adjustment, an l.shaped supporting bracket adj ustablyand reversibly mounted on said tongue, and a bearing for said actuating shaft adjustably mounted on said bracket.

6. The combination in a grain drill of the class comprising carrying wheels, a main frame, a tongue, draft connections, and furrow openers, of a rock shaft for adjusting said furrow openers, a worm segment on said rock shaft, a worm shaft mounted in bearings on said frame and providedwith a worm coacting with said segment, a bracket adjustably supported on said tongue, and a forwardly extending actuating shaft having a universal joint connection to said worm shaft, the forward end thereof being ad-l justably supportedon said bracket.

ln witness whereof, we have hereunto set our hands and seals.
